1 Digi Connect WAN Application Helper Configuring and Testing the Digi Connect WAN Cingular/Motient IP Address and Pre-configuration Information Ethernet Connectivity: Connect your workstation or device to the Digi Connect WAN via one of these methods: 1. Direct from workstation to Digi Connect WAN via an Ethernet crossover cable. 2. Via network hub or switch using a straight-thru Ethernet cable. Ethernet Port IP Addressing: Follow the Quick Start Guide and assign the Digi Connect WAN an IP Address. In most cases a static IP address is desired. DHCP Sever: The Digi Connect WAN/VPN includes a DHCP server and can provide IP address configuration to remote devices and/or workstations. DHCP server is on by default and is configured to provide workstation IP addresses starting at Static IP Addresses: If static IP addresses are used, disable the Digi Connect WAN DHCP server via Configure>Network>DHCP Server Settings and follow these directions: 1. In order to properly communicate via the Digi Connect WAN, your workstation should be in the same subnet as the Digi Connect WAN. The simplest way to accomplish this is to use the Digi Connect WAN s DHCP server. If you are using the DHCP server, and the Digi device is at IP address , you should configure your workstation to be something like: IP address: Subnet mask: Default gateway: (i.e. the IP address of Digi Connect WAN) 2. As shown above, any device using the Digi Connect WAN as a gateway via the cellular wireless network must have its default gateway configured to the Digi Connect WAN s Ethernet port IP address. 3. DNS Server IP addresses: If you plan to browse the Internet or make other outbound connections that utilize DNS names (e.g., ), the carrier s DNS server IP addresses should be entered into the workstation s IP configuration. For example, for most Cingular Blue APN types use &.11. DNS info can be confirmed once the Digi Connect WAN has connected to the cellular network using the Digi Connect WAN Web UI via Administration>System Info>Mobile. Page 1 of 6

2 Changing the Digi Connect IP Address: The Digi Connect WAN IP address settings can be changed using the built-in Web UI or via command line. Via Command Line: Use either the console port and a terminal emulation program or telnet to the Digi Connect WAN s IP address. Use the set net command similar to: set net ip= mask= gateway= Type set net with no parameters to verify the settings. Reboot the Digi Connect WAN by either re-powering or via the boot action=reset command. Via Web UI: Point your browser to the Digi Connect WAN s Ethernet port IP address, select Configuration>Network and enter the desired settings, as shown below. Press Apply, and then reboot the Digi Connect WAN for changes to take effect. You will lose connectivity to the unit until you reconfigure your workstation to be in the same subnet as the Digi Connect WAN; or use DHCP. APN Configuration In order to communicate via GPRS on a GSM network, the Digi Connect WAN must be configured for a certain APN (Access Point Name) type. Follow the steps below to configure the Digi Connect WAN for the imotient/cingular network. Connecting the Digi Connect WAN 1. Ensure the SIM is in place. If not, insert the SIM into the SIM garage. 2. Attach the antenna to the Digi Connect WAN. Place the Digi Connect WAN and/or antenna in a location that will ensure the best signal. 3. Connect the Digi Connect WAN Ethernet port to your workstation or device in the method mentioned above (either via hub/switch or direct via Page 2 of 6

3 crossover Ethernet cable). 4. Apply power to the Digi Connect WAN. After a few minutes observe the following: a. The green Ethernet link LED located on the Ethernet port should be on. If not, make sure you are using the proper cable. b. Signal Strength LEDs on top of unit should show 2-4 LEDs. If not, try repositioning the antenna and unit if necessary. Do not extend the antenna cable. Instead, reposition the Digi Connect WAN unit itself via longer Ethernet cable connection. c. Activity LED will be on solid for a few moments then go off. d. The Wireless Link LED on top of unit should go on solid once the APN type is properly configured. If not, verify the APN provisioning via Configuration > Mobile. e. Make sure it is set for the correct APN configuration. The proper selection in the Service Provider box is Cingular Wireless (Blue Network). f. The proper selection in the Service Plan box is Custom APN. g. In the Custom Plan Name box, enter the APN provided by imotient Solutions on the Device Activation spreadsheet. (For example: gprs02.motient.net) 5. If you changed the APN information or mobile provider, or IP address settings, reboot the Digi Connect WAN via Administration>Reboot. Page 3 of 6

5 Testing the Digi Connect from a Workstation Once the Digi Connect WAN is connected to the cellular network and is accessible from network devices connected to its Ethernet port, you can do some simple tests to verify communications through the device. A simple test is to connect out through the Digi Connect WAN to your imotient Host computer. Make sure your workstation s IP network is configured to use the Digi Connect WAN s Ethernet port IP as the default gateway. From the command line, execute a ping command to the IP address of the host computer on the imotient Tunnel connection. For example: ping You should see an echo response indicating that the data reached that IP address. Inbound connections require additional configuration to test. First, not all APN types allow incoming connections. Second, the Digi Connect WAN uses NAT (Network Address Translation)* to route traffic from the Public IP address on the cellular interface to the Ethernet port s private IP network. NAT provides two main benefits: Security: NAT hides the private IP addresses of the devices on the Digi Connect WAN s Ethernet network. IP Address Availability: IP addresses are in short supply and cost money. The Digi Connect WAN need be provided only one IP address from the wireless carrier. Port forwarding* entries are required to pass incoming traffic through the Digi Connect WAN to a device or workstation connected to the Digi Connect WAN s Ethernet port. * Note that the Digi Connect Remote Gateway (RG) does not support NAT or port forwarding. Refer to the Digi Connect WAN application guide on mobile terminated connections Page 5 of 6

6 for details on setting up inbound connections. If your account is set up to include a static IP for the mobile device, a simple test to verify the Digi Connect WAN is on the wireless network and is accessible is to ping the IP address from your imotient Host computer. For example, if your assigned static IP is : ping If the request times out, try adding a -w 5000 or -w to the ping command: ping -w Other application scenario examples, such as using the Digi Connect WAN for a backup wireless WAN connection, are available from Digi International.
